West coast of India has got a flatter continental slope as compared to East Coast, resulting into the long navigational channel on the West Coast Ports, such as New Mangalore Port and Cochin Port. Wave refraction takes place in the long navigational channel, as they travel, resulting in very good wave attenuation at the entrance to the Port. An attempt has been made to study this phenomenon. Wave propagation from deep water to the shallow coastal regions has different processes as compared to wave propagation from shallow region to inside the port or coastal area. In order to accommodate these processes two mathematical model MIKE 21 SW and MIKE 21 BW have been used. Wave transformation from deep water to mouth of navigational channel has been done using MIKE 21 SW model. Results of same indicate that WNW, West, 259°N (along the navigational channel), and WSW wave directions are predominant at the entrance to the channel. All these wave conditions are used for wave propagation along the navigational channel. Analysis of these data has indicated that wave propagation along the channel has maximum attenuation as compared to wave with some angle with channel alignment. It is also seen due to refraction of wave energy from the side slope of navigational channel, wave energy concentration is seen on side slopes. It can be concluded that long navigational channel is good from the wave tranquillity aspects.
